Abstract (en)

[origin: US4638140A] PCT No. PCT/JP84/00303 Sec. 371 Date Jan. 28, 1985 Sec. 102(e) Date Jan. 28, 1985 PCT Filed Jun. 12, 1984 PCT Pub. No. WO85/00025 PCT Pub. Date Jan. 3, 1985.A wire guide consisting of a V-groove-type guide, a device for supplying machining liquid, and a die-type wire guide removably attached at the lower surface of the V-groove-type guide causes increased machining accuracy while used in both non-taper machining and taper machining modes. The increased accuracy is achieved after the wire passes through the V-groove-type guide by using the die-type wire guide to return the wire to a straight path to improve the linearity of the wire and, accordingly, improve machining accuracy.
